3.A plane takes off which is carrying 10 passenger. As soon as the plane reaches the sky, a man hijacks it because there is a lot of money present in the plane. Before the takeoff of the plane, the hijacker had asked for 11 parachutes.
Once he killed everyone in the plane so that nobody could identify him. He took one of the parachute and jumped with the money.
So then why he asked for 11 parachutes when he needed only one?
The answer is asking for 11 parachutes, he made it seem like he planned on allowing the hostages to survive so the government wouldn’t risk tampering with any of them. If he had asked for just one, they would have known it was just for him and probably done something to it.
